Problems solved by technology

These microscope systems are generally expensive, and can produce inconsistent results, even when used by well trained personnel.
However, a numerical result for sperm count is not obtainable with this test kit, and it has no facility for assessing sperm motility.

Abstract

Test kits for assessing male fertility include a sample holder defining an object plane, a lens, and a two dimensional light sensor defining an image plane arranged along a common linear axis. The distance between the object plane and the image plane may be no more than 50 mm, and may be no more than 30 mm. A lens aperture may have an area of 1-10 mm2. The test kit may have a housing with a maximum linear dimension of no more than 100 mm. Processing circuitry may be provided that is configured to produce a sperm count and / or sperm motility measurements by processing image data from the two-dimensional light sensor.

Description

REFERENCE TO RELATED APPLICATION[0001]This application is related to U.S. Provisional Application Ser. No. 61 / 774,990 filed Mar. 8, 2013, and takes priority therefrom.BACKGROUND[0002]Field[0003]The embodiments disclosed herein relate to test devices and methods for assessing male fertility.[0004]Description of the Related Art[0005]Male fertility is generally assessed by counting the number of sperm per milliliter in a semen sample. Traditionally, this has been done manually by a trained andrologist. A semen sample is placed under a microscope, and the number of observed sperm are counted in a given area of view. This count is correlated to sample volume to produce a value for sperm per milliliter. In addition to sperm count, sperm motility is also a significant factor in assessing male fertility. A qualitative assessment of sperm motility can be made by visually evaluating the motion of the sperm in the sample under the microscope. These microscope systems are generally expensive, a...
